We report an unusual case of lupus flare induced by intravenous vancomycin in a patient with systemic lupus erythematosus. Due to methicillin resistant staphylococcus aureus in wound culture, intravenous vancomycin was administered to the patient. The patient had been on vancomycin for several days then she experienced fever, malar rash, and vomiting. Based on laboratory results, it was confirmed as lupus flare. Oral prednisolone was given to the patient for symptom control. However, when vancomycin was readministered, the patient had similar symptom to the previous one more intensively. Vancomycin was stopped then the patient became stable. This case report demonstrates that intravenous vancomycin may manifest as lupus flare in patients with systemic lupus erythematosus.
